Now having watched the video, I certainly have a better understanding of the combat profiles, and I like the concept a lot. I think I'm going to be pulling the Explorer profile most of the time, picking what I like from each skill type (concussive shot, incinerate, and biotic charge come to mind), but the other profiles would allow me to better specialize a skill set depending on my enemies.

It also appears that the six known squad mates will be all there is (Cora, Liam, Peebee, Drack, Vetra, and Jaal), so no "we have a legit tiny army; come at us" squad this time around. I like that, though; it'll make it easier to do stuff with ever member and make the bonds more unique.
